The domain of a graph is all the possible values of a graph on the x-axis
The range of a graph is all the possible values of a graph on the y-axis
Yes, this graph is a one to one function. All the given x values only have one y value. The vertical line test and the horizontal line test also show that it is a one to one function, because the lines do not touch two different points in the graph.
Self Assessment
Give an example from this assignment where you represented the same mathematical idea in multiple ways. The first way this idea was expressed was in the algebraic form of an equation, as y=√ x. Another way this idea was expressed was as a graph, shown in the photo given above.
Give an example from this assignment where you used mathematical vocabulary to demonstrate your understanding. I had used the vocabulary domain, range, function and one to one function to demonstrate my understanding. I had shown my understanding of the meaning of the words domain and range, and used them to explain my given equation and graph. I had also used the vocabulary “function” and “one to one function” to explain the meaning of a function, and if the graph fits the criteria to be a function. I had shown I understand what a function is, and how to tell the difference between a graph that is a function, and a graph that isn’t.
Give an example from this assignment where you used formatting to share the information in a clear and organized way. I had used formatting that organizes each section required in this edublog, making them easy to find and read. Each category has been put into bold lettering and underlined, with all needed information under with thin lettering. This makes it easy to navigate through the post, and find the needed information.
